Definitions

  • Fig. 9 shows a modification of Fig. 8 in which the two phase expander 28 is arranged to drive a second vapour compressor 30 connected in parallel with the main compressor 22. Both the expander 28 and the second vapour compressor 30 are of the Lysholm twinscrew type.
  • Refrigerant 134A as working fluid gives the following results: Overall Expansion Ratio Optimum Built in Expansion Ratio % Ratio Fig.8 13.63 3.20 23 % Fig.9 10.38 2.81 27 %
  • Such machines may also be used as the main expander in a system for the recovery of power from low grade heat sources such as geothermal brines, which has been called by the inventors the Trilateral Flash Cycle (TFC) system.
  • TFC Trilateral Flash Cycle
  • the circuit is shown in fig. 11 and its cycle in Fig. 12.
  • temperature changes and hence volume ratios are much larger and hence two or more expansion stages are needed operating in series.
  • a typical example of this is, as shown in Fig. 11, the case of a supply of hot brine in the form of saturated liquid at 150°C which is currently being separated from wet steam in a flash steam plant and reinjected into the ground at this temperature.
